Battery cover latch mechanism and portable electronic device using same

Abstract

The battery cover latch mechanism includes a housing, a battery cover comprising a clasp positioned thereon, a button assembled on the housing, a latching part slidably assembled on the housing; and resisting the button, and a resilient member assembled on the latching part, and resisting the housing. The clasp latches to the latching part to assemble the battery cover on the housing, when the button is pressed, the latching part compresses the resilient member, and the latching part is detached from the clasp by the button. The invention also discloses a portable electronic device using the battery cover latch mechanism.

         6 . The battery cover latch mechanism as claimed in  claim 5 , wherein the guiding block defines a first inclined plane thereon, the main plate defines a receiving portion therein, the receiving portion includes a second inclined plane resisting the first inclined plane. 
     
     
         7 . The battery cover latch mechanism as claimed in  claim 3 , wherein the latching part further comprises a post positioned on an end of the main plate, the housing further comprises a resisting plate positioned thereon, the resilient member coils around the post, and resists the resisting plate. 
     
     
         8 . The battery cover latch mechanism as claimed in  claim 3 , wherein the main plate defines two gaps corresponding to the resisting posts, the resisting posts respectively pass through the gaps. 
     
     
         9 . A portable electronic device, comprising:
 a housing;   a battery cover comprising a clasp positioned thereon;   a battery cover latch mechanism, comprising:
 a button assembled on the housing; 
 a latching part slidably assembled on the housing; and resisting the button; and 
 a resilient member assembled on the latching part, and resisting the housing; 
   wherein the clasp latches to the latching part to assemble the battery cover on the housing, when the button is pressed, the latching part compresses the resilient member, and the latching part is detached from the clasp by the button.   
     
     
         10 . The portable electronic device as claimed in  claim 9 , wherein the housing defines a latching hole and a through hole adjacent to the latching hole, and further comprises two supporting portions, one supporting portion symmetrically positioned at each side of the latching hole, and two resisting posts respectively aligning with the supporting portions, the latching part respectively resists the supporting portions and the resisting posts. 
     
     
         11 . The portable electronic device as claimed in  claim 10 , wherein the latching part comprises a main plate and a board perpendicularly extending from the main plate, the housing further comprises a baffle plate positioned thereon and adjacent to the through hole, the board resists the baffle plate configured to limit the sliding distance of the latching part. 
     
     
         12 . The portable electronic device as claimed in  claim 11 , wherein the button comprises a pressing portion and two limiting portions respectively extend from two ends of the pressing portion, the limiting portions resist the housing. 
     
     
         13 . The portable electronic device as claimed in  claim 12 , wherein the button further comprises a guiding block positioned between the limiting portions, the guiding block resists the latching part. 
     
     
         14 . The portable electronic device as claimed in  claim 13 , wherein the guiding block defines a first inclined plane thereon, the main plate defines a receiving portion therein, the receiving portion includes a second inclined plane resisting the first inclined plane.
